Abstract
Hygiene masks are worn in medical facilities by healthcare workers, patients, and hospital visitors. The three primary objectives of this presentation are to present on why and how a mask should be worn and what facial areas the mask protects. Usually, the mask covers the wearer’s nose and mouth. In this presentation, we first present the results of a physics experiment aimed at identifying the precise facial area that needs to be protected from the external environment. Second, we describe observational results relating to the macro air gap between the mask and facial surface that is present when wearing a mask. Third, we propose the most appropriate manner to wear a mask by considering the air gap between a mask and face and based on the analysis of our experimental and observational results.
